bdb021e6ac Massbus VAXen and PDP11: Cleanup RP device to allow simple replication 
Peter Allan analyzed the source code for the VAX780 simulator and
came up with a somewhat simple strategy to replicate the RP device
source code and to add another controller on an additional Massbus.

That initial strategy includes: Copying the pdp11_rp.c source module to
pdp11_rpb.c and making almost all global variables static as well as all
internal functions used in the RP device. All but the "DEVICE rp_dev",
that is, which now becomes "DEVICE rpb_dev" with a name of "RPB".

The change process was relatively simple although somewhat tedious and
wouldn't easily lend itself to manage future changes that might happen to
pdp11_rp.c.

The changes in this commit cleanup pdp11_rp.c so that changing it to
pdp11_rpb.c only need to affect 3 lines of code which will simplify
future maintenance of these modules.

bc5dcedf1d MicroVAX1: Remove DMA devices which weren't supported on MicroVAX I 
Removed TQ (TMSCP), TS (TSV11) and VH (DHV11) devices from this
simulator since these devices were never supported in release MicroVAX I
configurations.

Lacking a scatter/gather map, DMA devices needed to be written to
perform DMA into contigous buffers in low memory and then copy data
to user space buffers.  The MSCP protocol devices had specific support to
do scatter/gather transfers as part of the protocol.  The RL01/RL02 device
driver was modified to perform the appropriate buffer moves most likely
to prove the customer option to adjust their drivers actually worked.  In
any case, boot support for RL01/RL02 disks does not exist.
